SECTIONAL IBIEATER ROLL.

Application filed March a, 1923. Serial in. 622,885.

To all whom it may concern:

Be it known that we, GEORGE R. HANKS, STANLEY APGAR, ALFRED R. BENCH, and GEORGE L. BIDWELL, citizens of the United States, residing, respectively, the said GEORGE R. HANKS and STANLEY APGAB, at High Bridge, in the county of Hunterdon and State of New Jersey, the said ALFRED R. BENCH, at Easton, in the county of Northampton and State of Penns lvania, and the said GEORGE L. BIDWELL, at iegelsville, in the county of Bucks'and State of Pennsylvania, have jointly invented a certain new and useful Sectional Beater Roll, of which the following is a specification.

Beater rolls whereof the knives and their supports are integrally constructed of manganese steel have evidenced by long and continuous service greater efiiciency and otherwise marked superiority over the old types of rolls.

Manganese steel ofi'ers serious foundry and heat treatment problems especially in the case of castings of ponderous weight and intricate section.

We solve these problems and also provide for adjusting the efi'ective length of the beater roll by constructing the latter in roll sections which are counterparts or in other words interchangeable.

A further merit of the invention resides in the provision of simple, yet efi'ective means for justifying and preserving the alinement of the knives and for locking the sections collectively as a unit.

A further merit of the invention resides in the provision of means for relieving the spiders from driving strains and for reinforcing the knife-carryin elements.

One embodiment of t e invention is illustrated in the accompanying drawing,

wherein- Figure 1 is a longitudinal sectional view; and r Fig. 2 a cross sectional view.

According to our invention, interchangeable roll'sections 5 are provided the number of such roll sections varying according to the length of roll desired. Each roll section is a casting such as manganese steel or other shock and Wear resisting steel, including a knife-carrying roll or cylindrical portion 6,

a spider 7 and a hub 8. The hubs 8 are formed with one or more key seats 9 for use in establishing interlocking engagement with the shaft 10, and diametricall opposite each key-seat there is a counterba anoe provision 11.

The roll sections have webs 12 starting at the edges of the knife-carrying cylinders 6 and'vanishing in the bodies of t e spoke elements 13 of the spiders. As indicated in Fig. 2, the webs 12 are ofiset with respect to the center lines of the spokes, which arrangement operates to relieve the spokes and the spiders as a whole from driving strains and also aids in the uniform distribution of stresses transmitted by the knives 14.

The abutting edges of the roll sections are ground or' fini'shed and are substantially ground seated so that when two or more sections are assembled on a common center line support, such as the usual complemental shafi, the knives are co-extensive or continuous. In order to justify and to maintainthe alinement of the knives and also to lock the roll sections collectively as a unit, the spiders are formed with registering openings 15 for the passage of, for example, rods 16 the terminals of which are screwthreaded for co-operaticn with appropriate fastening provisions 17.

End plates or headers 18, with or with out the usual bangers 19, are secured tn the end roll sections, as by bolts fit).

aving described our invention, we claim 1. A beater roll embodying ground seated roll sections with integral hives and spokes with shaft receiving elements, and means for justifying and maintaining the alinement of the knives.

2. A beater roll embodying flush fittin open roll sections with integral knives an with integral shaft receiving elements, and means for justifying and maintaining the alinement of the knives, including means for securing the sections as a unit.

3. A beater roll embodying roll sections with integral knives, and means enga 'ng the end roll sections for securing all 0 the sections as a unit..

4.. A beater roll embodying interchangeare able flush, fitting roll sections, each section consisting of a unit casting havin a knife carrying peripher spokes, and hu 5. A beater rol embodying interchangeable ground seated roll sections with inteal knives and integral spiders, the spiders avin counterbalance provisions.

6. beater roll embodying interchangeable roll sections with integral knives and spiders, means for effecting substantially fluid-tight engagement of the sections, and means engaging the sections for lining up the'lmives.

7. A. beater roll embodying a shaft, and a series of roll sections each of which is independently locked to the shaft.

8. A beater roll embodying a shaft, a series of roll sections each of which is independentiy locked to the shaft, and means for securing the roll sections collectively as a unit.

9. A. beater roll embodying a shaft, knife newness carrying cylindrical sections mounted on the shaft, and individual and coliective locking provisions for said sections.

10. A beater roll embodying r011 sections whereof each is a unit casting of manganese steel with spaced radial supports, means for securing them in substantially fluid tight engagement, and means for relieving them of driving strains.

ILA beater roll embodyin mated roll sections the abutting faces of w ich are substantially ground seated.

12. A beater roll embodying a shaft, :1 series of roll sections interchangeably mounted on the shaft, and headers securedto the end roiisections. I

In testimony whereof, we afiix our signatures.
